In this research, non-fluorinated polyurethane/silica dioxide (PU/SiO) nanofibrous webs were prepared by electrospinning and hydrothermal treatment. Then the developed webs were laminated onto polyester woven fabrics to examine their practical applications in the textile area. Investigation for surface morphology, pore size, water contact angle (WCA) and hydrostatic pressure was done in detail to examine the waterproofness and breathability of the PU/SiO nanofiber webs and the laminated fabrics. The results showed that when Tetraethoxysilane concentration in electrospun solution was 6 wt%, the fibrous web exhibited the desirable morphology, mechanical properties and hydrophobicity. At this time, SiO₂ nanoparticles dispersed uniformly on and in PU nanofibers and fibers had a more uniform diameter. The composite laminated fabrics produced exhibited a value for hydrostatic pressure of 23.5 kPa with water vapor transmission rate (WVTR) of 5.19kg/m²/day.

在这项研究中，通过电纺丝和水热处理制备了非氟化聚氨酯/二氧化硅（PU / SiO）纳米纤维网。然后将显影的纤维网层压到聚酯机织织物上，以检查其在纺织领域的实际应用。详细研究了表面形态，孔径，水接触角（WCA）和静水压力，以检查PU / SiO纳米纤维网和层压织物的防水性和透气性。结果表明，当电纺丝溶液中四乙氧基硅烷浓度为6 wt％时，纤维网表现出理想的形态，机械性能和疏水性。此时，SiO ₂纳米粒子均匀地分散在PU纳米纤维上和之中，纤维的直径更均匀。所生产的复合层压织物在水蒸气透过率（WVTR）为5.19kg / m ² /天的情况下显示出23.5kPa的静水压值。
